[quoted lines by Alan Stern on 2015/02/11 at 14:45 -0500] >Does the poll return immediately after the URB is submitted, or is >there a delay? What if you try calling poll _before_ the URB is >submitted? poll() is used for the underlying event mechanism, so it's always being caled. The entire application (brltty, if you're curious) is a set of event handlers that come and go as needed. The signalfd notification is appearing on the very first call to poll() after the urb is submitted. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
